01503f8a7b Use an enum instead of an boolean for some flags 
They still only hold AL_TRUE or AL_FALSE, but some systems can't properly
handle atomic swaps of 1-byte types.

5736bbc3e4 Add a source property to skip channel virtualization for multi-channel buffers 
With virtualization disabled, channels are mapped directly from input to output
and any input channel that is missing an output is dropped. Any virtualization
effects (such as HRTF filters) for positional cues are also skipped.

The idea is to allow applications a way to play pre-filtered audio that channel
vitualization effects could interfere with.
